original application tiled may 13, 1921, Serial No. temes. ADivided and this application filed November 7, `1922. Serial No. 599,553.

To all 'whom it may concern.'

Be it known that l, HARRY B. Ross, a citizen of 'the United States, residin at Denver, in the county of Denver and tate of Colorado, have invented anew and Improved Washing Machine, of which the following is a specification.

My present invention has for its object to provide certain new and useful improvements in washing machines and the present invention has especially for its object to provide certain new and useful improvements in the pounders employed in such machines.

ln my application Serial No. Lt69,198, filed May 13, 1921, I have disclosed an improved .washingmachine in which the present invention is especially adapted for use and the present application is a divisional part of mfy original application Serial No. l69,198 a oresaid. ln such original application l have disclosed a washing machine which comprises generally a tub or reservoir for the water in which is rotatably mounted a perforated washing and drying cylinder and on the edge of which tub is mounted a support that sustains the power mechanism for turning the cylinder and also for operating the crank shaft on which the pounders are located.

ln my present application l make no claim to the construction of the washing machine as a whole as that constitutes the subject matter of my original application, the present application being confined to the pounder construction per se,

llt is therefore an object of my present invention to provide a pounder in the nature of a vacuum cup device for engaging the fabric to ed'ect the surging of the same in the vessel in which the treatment occurs so as to force air and suds through the fabric and thereby edect the cleansing action.

ln its generic nature, my present invention comprises a vertically movable rod to the lower 'end of which is secured a rubber vacuum cup, there being an outer vacuum cup slidable on the rod and adapted to receive the rubber cup.

ln the drawing Figure 1 is 'a central vertical section, parts being in elevation, showing my invention in use in connection with the washing machine of my original application aforesaid.

Figures 2 and 3 are detail vertical sections illustrating the action of the vacuum cup members.

In the drawings in which like numerals of reference indicate like parts in all of the figures, 1 is the tub or tank which is mounted in any suitable way on any suitable base or support 2 and in which the combined washing and drying cylinder 3 is mounted for rotation on a vertical axis.

et represents the support for the crank shaft 5 to which the vertical pounder rods t are pivoted as at 7. The rods swing loosely on their pivots and carry the rubber vacuum cups 8 which are attached to the lower ends of the Enclosing the cups 8 are metallic cups 9 which have sleeves 10 to slide freely up and down on the rods 6.

ln using the invention water is placed in the tank 1. 'llhe water level should not be abovethe bottom edge of the rim of the tank so that the cups 8 when at the upward limit of their stroke, will-be out ofthe water and thus enable air to dow into thecups at the end of the up stroke of the plunger rod 6. After the water has been brought to the proper level, the cups are then set straight down into the cylinder 1 on top Vof the clothes and power is applied to turn the crank shaft 5, thus working the cups 8 and 9 up and down by the action of the cranks.

lt will be observed, that by my construction of vacuum cups, the neck of the outer metallic cups, sliding 'reel on the rod 6, in cooperation with the rub er suction cups 8, allows vthe cups to give to ti htly packed clothes or any obstruction to t e stroke of the cranks; also air trapped can escape through the loose neck 10, then when the cranks are on the upward stroke, the metallic cups remain down until the rubber piston cups 8 move up until an air tight connection between the cups 8 and 9 is effected, thereby intensifying the vacuum which pulls the suds through the clothes rapidly and is quite a practical improvement over the common simple vacuum cups heretofore used in washing machines of this general type.

From the foregloing description taken in connection with t e accompanying drawing, it is thought the complete construction, operation and advantages of my invention will be readily understood.

What I claim is:

l. lln apparatus of the class described, a vacuum cup clothes working member comprisin a rod, a rubber vacuum cup on the end o 'said rod, an outer vacuum cup slidliti@ lit) able onsaid rod and enclosing said rubber cup 'said rubber cup being adapted, vWlien sald outer cup is in the lowermost positlon end o f said rod, an outer vacuum cup slidable on said rod, and enclosing said rubbercup, said rubber cup being adapted when said outer cup' is in the lowermost position to- Veffect a sliding engagement with the same, substantially as shown and described.

lslidable on said rod and enclosing said inner cup, said inner cup adapted, when said outer cup is in the lowermost position, to eifect engagement with the same, substantially as -shown and described.
